He's referring to 802.1x, which is a form of port-based network access/admission control (NAC). It uses EAP (Extensible Authentication Protocol - actually EAPOL [EAP over LAN]) to require authentication before the supplicant is given access to the LAN. That's the theory - but I've no idea how it works in practice with CentOS. -- Best, --- Les Bell [+61 2 9451 1144] [http://www.lesbell.com.au]
